Hi, I recently purchased an Arduino Nano 33 IoT for a Bluetooth project I am working on. I am trying to get my Nano 33 IoT to control the color of an LED strip based on Bluetooth inputs from my iPhone.
At first, I tried using the popular Blynk app because of its many widgets, however, I was unable to find any way to connect to it over bluetooth with my Nano 33 IoT...
If this can't be done, are there any other apps/interfaces that I can use to send inputs to my Nano 33 IoT over bluetooth?
I believe your Nano is BLE. If that is the case, you need to ensure that the Blynk app is BLE compatible. The only BLE app that I know of is that by Kai Morich. There are probably others.
The Nano33 and other MKR boards that use the WiFiNINA library only support BLE and not bluetooth classic.
There have also been problems with the firmware which are easily solved. Firmware Update 1.2.1 - available now, with BLE mode
I guess the ESP32 on the board is only WFi/BLE. However, there is still no Blynk example for BLE for the Nano 33 IoT.
In the Blynk github library, under the examples folder there is a list of folders of Blynk examples for different forms of communication (WiFI, bluetooth, BLE, etc). For example, under the Boards_WiFi example, there is a Blynk WiFi example for the MKR WiFi 1010 which works on my Nano 33 IoT too because they have the same ESP32 module.
But the problem is that under the Boards_Bluetooth folder, there is no BLE Blynk example for the Nano 33 IoT or MKR WiFi 1010...
In addition, there is a BLE Blynk example for a standalone ESP32 board, however, that doesn't work on my Nano 33 IoT.
